A polyfluoroalkyl allyl compound represented by the general formula:
CF.sub.3(CF.sub.2).sub.n(CH.sub.2CF.sub.2).sub.a(CF.sub.2CF.sub.2).sub.bCH.sub.2CHCH.sub.2[I]
(n: 0 to 5, a: 1 or 2, b: 0 to 3). The polyfluoroalkyl allyl compound is produced by reacting a carboxylic acid allyl adduct represented by the general formula:
CF.sub.3(CF.sub.2).sub.n(CH.sub.2CF.sub.2).sub.a(CF.sub.2CF.sub.2).sub.bCH.sub.2CHICH.sub.2OCOR[II]
(n, a, and b are as defined above, and R: a C.sub.1-C.sub.3 alkyl group) with a transition metal. This method for producing provides a polyfluoroalkyl allyl compound used as a synthetic intermediate for a fluorine-containing alkylsilane compound that can remove free iodine derived from the raw material compound, before a hydrosilylation reaction is performed, without using a metal reagent having a high environmental impact, and that has excellent handling properties.
